1. The measurement of chemical persistence in the field by benchmarking : Theory and Experiment
Sammanfattning : Persistence is one of the core criteria in chemical exposure and hazard assessment. It is often defined as the half-life for the removal of a chemical from a specified environment by transformation. Chemicals with long transformation half-lives may pose high risks for wildlife or humans and be subject to long-range transport to remote areas. LÄS MER
2. Exploitation of interactions with the neonatal Fc receptor to manipulate biological half-lives for therapeutic applications
Sammanfattning : Protein engineering provides powerful tools to create useful proteins with desired properties. In this thesis, rational design principles have been used for development of fusion proteins that can interact with the neonatal Fc receptor (FcRn) for potential medical applications. FcRn is widely expressed in the human body. LÄS MER
3. How to estimate environmental persistence : Understanding persistence of organic micropollutants in rivers from a multidisciplinary perspective
Sammanfattning : Organic micropollutants such as food additives, pharmaceuticals and personal care products are found in rivers worldwide. Persistence is a key criteria in chemical risk assessment as micropollutants that are persistent pose an exposure hazard to humans and the environment. LÄS MER
4. Design, Synthesis and Evaluation of Photoswitches for Molecular Solar Thermal Energy Storage Systems
Sammanfattning : To meet the future energy demands and handle climate changes, new sustainable energy sources must be developed. Over the last decades, great scientific progress on harvesting solar energy has been made, but storing the energy is still a challenge. LÄS MER
5. On Alpha-decay and Alpha Clustering
Sammanfattning : The half-life for the Alpha-decay of 212 Po is calculated within a harmonic oscillator representation. Clustering induced by the nuclear interaction appear by considering alarge configuration space. The role of clusterisation in the alpha-decay process isclearly demonstrated. LÄS MER
